Serial No. 750,283. 4

To (ill whom it may concern:

Be it known that we, \Vrumur CLEVELAND and Jason R. Ocnnzoa, citizens of the United States, residing at Glenville, in the county of Clay and State of Nebraska, have invented certain new and useful Improvements in Radiators, of which the following is a specification, reference being bad to the accompanying drawings.

This invention relates to improvements in radiators adapted for 'use upon automobiles or the like, for cooling the water which is circulated throngh'the \vater.jack-.

ets of the engine cylinders.

An object of this invention is the provision of a radiator comprising a plurality of sections dctachably connected together, whereby the radiator may be readily taken apart when it is desired to repair the same or replace any of the water tubes.

A still further object of this invention is the provision of novel means whereby tight joints are provided between the several sections to prevent the water from escaping from the radiator.

\Vith these and other objects in view, our invention consists in certain novel constructions, cmnbinations, and arrangements of parts, to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which Figure 1 is a front elevation showing the sections of the radiator disconnected; Fig. 2 is a fragmentary vertical section. of the sections when connected; Fig. 3 is a perspective view of the means forsecuring the lower ends of the tubes to the lower wall of the intermediate or central section of the radiator.

Referring morev particularly to the drawings, the letter A designates the upper section of the radiator, B, the intermediate or central section, and C, the lower section thereof. The central section B comprises end walls 1, a top wallfl and a bottom wall 3, the end walls having connected thereto a plurality of horizontal radiating plates 4 which are spaced vertically and are provided with a plurality of vertically alined openings 5. The top wall 2 of the central section is provided with a plurality of threaded openings 6 which are disposed in vertical alinement with the openings 5 in the plates 4, and the bottom wall 3 is also rovided with a plurality of threaded openings 7 disposed in vertical alinement with the openings in the plates, the openings 7 in the bottom wall of the section being slightly larger in diameter than the openings in the top wall thereof. Threadably connected in each of the openings 7 in the bottom wall 3 is an exteriorly and interiorly threaded sleetge 8, the exterior threads of each sleeve being adapted to engage the threads of the opening the sleeves being formed with enlarged heads 9 at their upper end which are adapted to rest against the upper face of the bottom wall 3 to limit the movement of the sleeves. The enlarged head 9 of'each of the sleeves is formed with an inwardly extending annular flange 10, which is adapted to form a seat for a gasket 11. through the sleeves 8 and the alined openings in the plates 4, are a plurality of wa ter tubes 12 which are threaded as at 13, at their upper ends for engagementwith the threaded openings (3 in the upper wall of the section. To provide a water tight joint between each of the openings 7 and the lower ends of the tubes 12, an exterionly threaded collar 14 is provided for threaded engage lnent with the interior threads of thesleeve 8 in each opening, the inner periphery of the collar being adapted to frietionally engage the outer peri hery of the lower end of the pipe 12, and the edge of the collar being adapted to 'bear against the washer 11 to spread the same and force it against. the

periphery of the tube. The end members 1 of the intermediate section are formed of spaced walls 15, and horizontal and apertured supporting plates 16 are dispose tween the spaced walls 15 and project outwardly from the ends opposite of the section B whereby the radiator may be secured to the frame of the automobile.

The upper section A comprises a bottomless water chamber which is provided with an inlet pipe 17 through which the water from the jackets of the engine enters, the chamber pipe 18 which is provided; with a suitable cap 19. Thcopposite ends of the upper section A are provided with suitable transversely extendin boxings being o intermediate section, ner walls of the boxings and the side walls of the upper section above the lower edge 11o Disposed d be being also provided with a filling angular boxings 20, the 105 a width substantially the, distance between the spaced walls 15 of the. and secured to the ina gasket. 22. Extending downwardly from the boxings 20 are conneotin bolts 23 which are adapted toextend trough the plates 16 between the walls 15 of the central section and project below the'bottom of the central section. v

The lower section 0 of the radiator comprises a top open water chamber and is provided with an outlet pipe 24 which leads to the water jackets of the engine,- the lower section being provided with spaced end walls 25, the outer walls of which are provided with upwardly extending flanges 26 which are adapted to engage the outer end walls 15 of the central section. Formed on the in ner end walls 25 and the side walls of the bottom section is an inwardly extending flange 27, the flange 27 being spaced slightly from the upper edge of the section to form a seat for a gasket 28. When the sections are connected, the gasket 22 is disposed be: tween the flange 21 of the upper section and the upper wall of the intermediate section, to form a tight joint between the sections, and the gasket 28 isdisposed between the flange 2? of the lower section and the lower wall of the upper section, to form a tight joint between the lower section and the intermediate section. The lower ends of the bolts 23 project through the bottom wall of the lower section, and threaded u on the lower ends of the bolts are suitab e wing nuts 29 which are adapted to bear against the lower wall of the bottom section to secure the sections of the radiator together.

Should any of the tubes 12 become broken, it will only be necessary to remove the lower section of the radiator, whereuponthe collars 14 may be removed from the lower ends of the broken tubes so that the tubes may be rotated to unthread the upper ends thereof from engagement with the threaded 0 enings 6 in the upper wall of the interme iate section whereupon the :tubes may be removed and new ones replaced.

It will be seen that the water circulates through the radiator in the ordinary manner, that is, it enters the upper water chamber, whereupon it flows througli the tubes.

l2 and then flows back to the water jackets through the outlet pipe 24:.

Having thus fully described our invention ner walls, said lower section having spaced walls at opposite sides thereof and adapted to overlap the walls of the intermediate section the inwardly directed flanges of the upper section being adapted to rest upon the top of .the intermediate section, while the boxings of such upper section are adapted to overlap the inner walls of the spaced sides of the intermediate section and rest upon the outer walls, the inner wall-of the lower section being provided with an inwardly directed flange on which the base of the intermediate section is adapt-ed to rest, and clamping means positioned between the spaced walls of the intermediate section and beingoper atively engaged with the boxings of the upper section and with the lower sect-ion whereby the several sectionsare maintained in op erative relation.

In testimony whereof we hereunto aflix our signaturesin the presence of two witnesses.
